    Pipeline Reliability: An Investigation of Pipeline Failure PE100

    Each year there are hundreds of pipeline failures, resulting in pollution, loss in transportation capacity, loss of gas availability, and costly repair expenses. Of course, most of the failures occur on onshore pipelines, because they cover a much greater area, but failures on offshore lines normally take longer to repair and therefore are more serious in terms of business interruption.
